The PackOut Ultralight Stuff Sack is the perfect accessory for sorting and organizing ultralight backpacking gear. Our lightest stuff sack, the ounce-saving, semi-translucent diamond ripstop materials feature a water-resistant design for easy packing and protection from the elements. The reflective drawcord cinch closure makes finding gear in low-light conditions easy, and the polyurethane coating protects against debris and moisture.
